For the odd parity ground state, the Berry curvature \(\Omega (k)\)  is plotted in Fig. REF (a) as a function of the magnitude of the wave vector \(k\)  plotted from the valley center (the Berry curvature is isotropic in the minimal model) for \(N=16\) . The position of the maximum in \(\Omega (k)\)  is given by \(k_{\mathrm {max}} \approx s_N k_c (\Delta /\gamma _1)^{1/N}\) , \(s_N = ((N-1)/(2N+4))^{1/2N}\) , which moves from \(k=0\)  to \(k = k_c\)  as \(N\)  increases [1]}, [2]}, [3]}, [4]}. The integral of \(\Omega (k)\)  with respect to the wave vector area also increases with \(N\) , as characterized by the Chern number per flavor which has magnitude \(N/2\)  [5]}, [6]}, [7]}.
